        <footnote id="F2">Each share of phantom stock converts into one share of common stock and was the economic equivalent thereof.  The reporting person settled 2,377 of his shares of phantom stock, which were held in the PNM Resources, Inc. Executive Savings Plan,  for cash based on the closing market price at year-end, 12/31/10, of the company's common stock on the date of the transaction.  The  reporting person made such settlement pursuant to the one-time election that was available to participants in connection with the merger of the PNM Resources, Inc. Executive Savings Plan I with the PNM Resources, Inc. Executive Savings Plan II, which was completed in December 2008.</footnote>
